Adjuvant Radiotherapy May Not Lengthen Mesothelioma Survival, Study Shows

adjuvant radiotherapy

Having adjuvant radiotherapy after surgery may not help mesothelioma patients live any longer according to researchers at Duke and Stanford Universities. Researchers used a database of pleural mesothelioma patients from Duke and a national registry to conduct the analysis.  They compared the outcomes of patients who had radiation after surgery (adjuvant radiotherapy) with the outcomes of those who did not.  While radiotherapy may help reduce mesothelioma symptoms for some patients, the results of the study suggest that it is unlikely to extend survival. Radiation for Mesothelioma and Its Symptoms Radiotherapy is a mainstay of cancer therapy for certain kinds of cancer. But the irregular shape and aggressive nature of mesothelioma tumors makes them less than ideal for radiation treatment.  Pleural … Continue reading Adjuvant Radiotherapy May Not Lengthen Mesothelioma Survival, Study Shows »

Triple-Modality Therapy May Improve Mesothelioma Outcomes, Study Suggests

triple-modality therapy

A Canadian study suggests that triple-modality therapy with radiotherapy, immunotherapy, and surgery may extend the lives of people with malignant pleural mesothelioma.  Pleural mesothelioma is an intractable cancer with a poor prognosis. It mainly affects people who have lived or worked around asbestos.  There is no cure for mesothelioma. People who have the best mesothelioma outcomes usually have a combination of treatments.  Now, scientists at Toronto General Hospital’s Research Institute say a triple-modality therapy they tested in mice might have the power to extend human lives, too. Multi-modal Mesothelioma Treatment Pleural mesothelioma is a fast-growing cancer that starts on the membrane around the lungs. Many mesothelioma patients die less than a year after diagnosis.  There is no single accepted treatment … Continue reading Triple-Modality Therapy May Improve Mesothelioma Outcomes, Study Suggests »

Radiotherapy Outcomes in Mesothelioma Linked to Metabolism

radiotherapy outcomes

Italian researchers say metabolic markers may hold the key to predicting radiotherapy outcomes in people with mesothelioma. Metabolism is the process by which cells produce energy. Metabolism is necessary for cancer cells to live. Mesothelioma cells metabolize faster than healthy cells.  Radiotherapy affects cancer cell metabolism. A new study shows that compounds produced during metabolism may impact radiotherapy outcomes. It suggests that a patient’s metabolic profile – or metabolome – could help doctors choose good candidates for radiation. Radical Hemithoracic Radiotherapy and Mesothelioma  Pleural mesothelioma is a rare lung-related cancer caused by asbestos exposure. There is no cure for mesothelioma. Most mesothelioma patients have a combination of therapies. Radiation is one of the methods doctors use to help slow its … Continue reading Radiotherapy Outcomes in Mesothelioma Linked to Metabolism »

Focused Radiation After Chemotherapy May Improve Mesothelioma Survival

focused radiation after chemotherapy

New research suggests that mesothelioma patients who have focused radiation after chemotherapy may live longer with slower disease progression than those who have other therapy combinations. Researchers used two kinds of focused radiotherapy (FRT) in the study. One was stereotactic body radiotherapy (SBRT) and the other was hypo-fractionated radiotherapy. Both treatments deliver a deadly dose of radiation into tumors while sparing normal tissue.  Italian researchers say giving focused radiation after chemotherapy makes it even more effective against mesothelioma that is not yet widespread.  Radiotherapy for Pleural Mesothelioma Radiotherapy is one of several possible treatments for mesothelioma. Most patients start with chemotherapy. But chemotherapy has limited effectiveness. Increasingly, researchers are looking for other approaches to combat mesothelioma.  Most patients get the … Continue reading Focused Radiation After Chemotherapy May Improve Mesothelioma Survival »

Novel Strategy May Improve Immuno-radiotherapy for Mesothelioma

Immuno-radiotherapy for Mesothelioma

Canadian scientists say suppressing certain kinds of immune system cells could improve the effectiveness of immuno-radiotherapy for mesothelioma. Mesothelioma is a fast-growing membrane cancer caused by asbestos. Doctors have not found a single therapy that can beat it. For most patients, a combination of treatments offer the best survival odds. Immuno-radiotherapy for mesothelioma combines two types of treatments. Immunotherapy drugs activate the immune system while radiation attacks the tumor directly.  Mesothelioma tumors fight back against both kinds of treatments. But researchers testing a combination of the two may have found a way to make it even more powerful. How Immuno-Radiotherapy for Mesothelioma Works Malignant mesothelioma is one of the most treatment-resistant cancers. Doctors have to attack it from many different … Continue reading Novel Strategy May Improve Immuno-radiotherapy for Mesothelioma »

Proton Therapy for Mesothelioma: New Consensus Statement

proton therapy for mesothelioma

A group of international experts in radiation oncology say proton therapy for mesothelioma may be a safer alternative to standard radiotherapy.  Proton therapy uses protons instead of photons to destroy mesothelioma tumor cells.  The group evaluated both types of radiation therapy. They conclude that proton therapy for mesothelioma is less likely to damage the opposite lung and other organs.  What is Proton Therapy? Conventional radiation therapy for mesothelioma uses photons. A radiation oncologist delivers photons into the tumor with a linear accelerator. The photons or X-rays permanently damage the DNA. Damaged mesothelioma cells cannot grow and divide normally and the cells die.  The downside of standard radiation therapy is that normal tissue absorbs some of the damaging photons, too. This … Continue reading Proton Therapy for Mesothelioma: New Consensus Statement »

Radiotherapy Before Mesothelioma Surgery May Not Be Worth the Risk

Radiotherapy before mesothelioma surgery

Cancer doctors at Mayo Clinic say they do not plan to start routinely performing radiotherapy before mesothelioma surgery. The idea is based on a radiation protocol called SMART. The team monitored how well the SMART protocol worked among their pleural mesothelioma patients over a one year period.  The Mayo doctors acknowledged that radiotherapy before mesothelioma surgery can sometimes improve outcomes. But too many of their patients developed serious complications. In a recently-published article, the team concludes that SMART may not be worth the risk for most patients.  The SMART Way to Treat Mesothelioma? Pleural mesothelioma grows on the membrane that surrounds the lungs. Mesothelioma tumors lie close to the lungs and heart and may spread to one or both lungs. … Continue reading Radiotherapy Before Mesothelioma Surgery May Not Be Worth the Risk »

Targeted Radiotherapy for Mesothelioma May Extend Survival in the Right Patients

targeted radiotherapy for mesothelioma

A meta-analysis conducted by some of the country’s top cancer researchers says targeted radiotherapy for mesothelioma can help some people live longer. It is the first such analysis of targeted radiation after lung-sparing mesothelioma surgery. The team focused on intensity modulated radiation therapy (IMRT). IMRT is more precise than earlier forms of radiation treatment.  The new article appears in Practical Radiation Oncology. It is a meta-analysis of ten smaller studies. The researchers conclude that healthier surgery patients could safely consider targeted radiotherapy for mesothelioma. Making Radiotherapy Less Toxic In the past, radiation for mesothelioma has sometimes done more harm than good. Earlier types of radiation treatment were not as precise as IMRT. When radiation spills over into healthy tissue, it … Continue reading Targeted Radiotherapy for Mesothelioma May Extend Survival in the Right Patients »

Drug May Make Mesothelioma Cells More Sensitive to Radiation

sensitive to radiation

Scottish cancer researchers say they have found a way to make mesothelioma cells more sensitive to radiation.  Radiotherapy is one of the tools doctors can use to help slow progression of the asbestos cancer. It can also help alleviate mesothelioma symptoms.  But proteins expressed by mesothelioma cells can make them less sensitive to radiation. The Glasgow-based research team is getting around this protection with a sensitizing drug. The drug mimics a process that already happens in healthy people. Radiotherapy in the Treatment of Mesothelioma Radiotherapy is not usually the primary treatment for malignant mesothelioma. Most mesothelioma patients have chemotherapy as their first-line treatment.  But newer technology means that radiation can be more targeted than it used to be. This means … Continue reading Drug May Make Mesothelioma Cells More Sensitive to Radiation »

IMRT for Mesothelioma: Barriers to Completing Treatment

PD-L1 inhibitor nivolumab

MD Anderson researchers say too many patients who might benefit from IMRT for mesothelioma never complete the treatment. The problem could be impacting their survival. Intensity Modulated Radiotherapy (IMRT) is a type of targeted radiation. It is designed to direct as much radiation as possible into the mesothelioma tumor without harming the surrounding tissue.  Patients who have a combination of surgery, chemotherapy, and IMRT for mesothelioma have the best odds of survival. But at MD Anderson Cancer Center, only two thirds of eligible patients completed IMRT after mesothelioma surgery. The new study aimed to find out why. Trimodal Therapy and Mesothelioma Survival Malignant mesothelioma rarely responds to a single cancer therapy. Trimodal therapy combines several different treatments to maximize success.  … Continue reading IMRT for Mesothelioma: Barriers to Completing Treatment »
